Analysis of Color Processing Technology for LED Electronic Display Screens

LED electronic display screen integrates microelectronics technology, computer technology, information processing, and has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc. LED display screens are widely used in commercial media, cultural performances, sports arenas, information dissemination, news releases, securities trading, etc., and can meet the needs of different environments. LED electronic display screens, from the initial monochrome display screen, two-color display screen, three-primary color display screen, to today's multi-primary color display screen, have accumulated various color processing technologies, becoming one of the core technologies of LED display screens.

LED display screen is an electronic display screen composed of LED dot matrix, which changes the display content form such as texts, animations, pictures, and videos through the timely switching of red and green light beads, and performs component display control through modular structure. It is mainly divided into display modules, control systems, and power systems. The display module is composed of LED light dot matrix to emit light; the control system regulates the on and off situation in the region to realize the conversion of the screen display content; the power system converts the input voltage and current to meet the needs of the display screen.

Matching of white field color coordinates for LED display screens

The matching of white field color coordinates is one of the most basic technologies for full-color LED screens, and many LED electronic display screen manufacturers have begun to standardize the full-color screen color matching process. However, some manufacturers often sacrifice the grayscale level of some primary colors to match the white field color coordinates, which results in the comprehensive performance not being improved.

Selection of primary color wavelengths for LED display screens

LED electronic display screens have been widely used in various fields with their own characteristics, and the required primary color wavelengths of LEDs are also different in different fields. How to choose LED primary color wavelengths to achieve better visual effects depends on usage and occasion.

Color rendering processing for LED display screens

The birth of pure blue and pure green LEDs has made full-color LED screens popular in the industry because of their wide color gamut and high brightness. However, there is a significant deviation in rendering human skin color, and thus color rendering processing technology has emerged.

Static screen in LED advertising screen design is the counterpart of dynamic screen (scanning screen). The static screen refers to all the light points lighting up at the same time when the display screen is displaying. The scanning screen utilizes the persistence of vision of the human eye, and lights up each row of the LED electronic display screen separately in a very short time cycle.

LED screens are driven by duty cycle, so the brightness of the display is closely related to the lighting time cycle. In the case of the same brightness of the light-emitting tube, the static screen has higher brightness than the dynamic screen, so static screens are generally used in outdoor screens, and dynamic screens are used in indoor screens to save driving costs.
